ered to be improper and may result in personal injury or property damage. No liability will be
assumed for damages resulting from improper use.
This device may be used only by persons with sufficient physical, sensorial, and intellectual
abilities and having corresponding knowledge and experience. Other persons may use this
device only if they are supervised or instructed by a person who is responsible for their safety.
DANGER!
Danger for children
Ensure that plastic bags, packaging, etc. are disposed of properly and are not
within reach of babies and young children. Choking hazard!

CAUTION!
Possible hearing damage
The device can produce volume levels that may cause temporary or permanent
hearing impairment. Over an extended period of time, even levels that seem to
be uncritical can cause hearing damage.
Decrease the volume level immediately if you experience ringing in your ears or
hearing impairment. If this is not possible, keep a greater distance or use suffi‐
cient ear protectors.
NOTICE!
Operating conditions
This device has been designed for indoor use only. To prevent damage, never
expose the device to any liquid or moisture. Avoid direct sunlight, heavy dirt, and
strong vibrations.

4 Installation
Unpack and check carefully there is no transportation damage before using the unit. Keep the
equipment packaging. To fully protect the device against vibration, dust and moisture during
transportation or storage use the original packaging or your own packaging material suitable
for transport or storage, respectively.
Establish all connections as long as the unit is switched off. Use the shortest possible high-
quality cables for all connections.
WARNING!
Risk of injury caused by falling objects
Make sure that the installation complies with the standards and rules that apply
in your country. Always secure the device with a secondary safety attachment,
such as a safety cable or a safety chain.

CAUTION!
Risk of injury due to heavy weight
Due to the heavy weight of the device, at least two persons are required for trans‐
port and installation.
NOTICE!
Possible property damage by magnetic fields
Loudspeakers produce a static magnetic field. Therefore, maintain an appropriate
distance to devices that can be adversely affected or damaged by an external
magnetic field.

4.1 Tips on handling speakers
We recommend you to set up the speakers in a way, that the sound signals can reach the audi‐
ence unobstructedly. It will often be helpful to mount the speakers on tripods. Thus, the sound
will be evenly spread with maximum range throughout the audience area.
Always use high grade cable to connect your equipment. Otherwise you won't reach max‐
imum sound quality.
For optimum results both impedance and power handling of the speakers must match the
requirements of the amplifier. Always follow the technical specifications of the speakers! The
overall impedance of the connected loudspeakers must not deceed the minimum output
impedance of the amp. The amps RMS output power should be 50 % above the power han‐
dling capacity of the connected speakers.
If you notice distortion during operation, either the amp or the speaker is overloaded. This may
permanently damage the amp or the speaker. Always reduce the volume when you hear dis‐
tortion.

4.2 Connections for wiring method ‘Bass to 1’
In order to use the connections for the wiring ‘Bass to 1’ rotate the connection panel cover in a
way that the notches are in horizontal position.
1, 2 NL4 connections, wired in parallel (1+/1– to woofer; 2+/ 2– interconnected)
Installation
Achat 118
13

With this connecting method you can connect the woofer directly using a two-wire cable
(wires 1+/1–). If using four-wire cables you can use those kind of top speakers that receive their
signals through wires 2+/ 2– and interconnect wires 1+/ 1–. The woofer is connected to wires
1+/ 1– and interconnects wires 2+/ 2–. The order in which the speakers are connected doesn't
matter, but the minimum load impedance of the amplifier must never be deceeded.

4.3 Connecting the Achat system
To use the connections for the Achat wiring system rotate the connection panel cover in a way
that the notches are in vertical position.
3, 4 NL4 connections, wired in parallel (2+/ 2– to the woofer; 1+/1– interconnected)
Installation

These connections enable a simple wiring with four-wire cables, as the top speakers receive
their signals via cores 1+/ 1– and the wires 2+/ 2– interconnect. The woofer is connected to
wires 2+/ 2– and interconnects wires 1+/ 1–. The order in which the speakers are connected
doesn't matter, but the minimum load impedance of the amplifier must never be deceeded.
